Bengaluru's founding myths are garages and audacity. Infosys — seven engineers, $250, a move to Electronic City in 1983 and India's first NASDAQ listing. Wipro — a vegetable-oil firm from 1945 that Azim Premji steered into software until it became one of the IT big three, run from Sarjapur Road. Biocon — a 25-year-old brewmaster, a rented garage, ₹10,000, and India's biopharma industry. Together they industrialised Indian talent export and trained the managers who staff every later cluster.

The quiet giant cluster. Texas Instruments' 1985 design centre — chip layouts beamed to Dallas from a rooftop dish — was the first time a multinational trusted India with real R&D. Today more than a thousand global capability centres employ a huge share of the city's million tech workers: SAP Labs and GE's research campus in Whitefield, Goldman and Walmart along ORR, and Bosch, whose 1950s Adugodi pump works is now the 76-acre Spark.NXT software campus. GCCs are Bengaluru's safety net and its talent gym.

Aerospace is the city's oldest industry. HAL has built aircraft on Old Airport Road since 1940; ISRO has run India's space programme from Antariksh Bhavan since 1969, putting a probe around Mars for less than a Hollywood film. That state-built base — plus DRDO labs and Bharat Electronics — now feeds a private spacetech wave: Pixxel's hyperspectral imaging satellites, Bellatrix's in-space propulsion and Digantara's space-surveillance network all draw on the same engineer pool.

The cluster that made the city famous. Flipkart (2007) proved Indians would shop online and its $16B Walmart exit armed a generation — the 'Flipkart mafia' founded PhonePe, backed dozens more, and staffed the rest. Swiggy pivoted from a failed courier into every kitchen; Myntra, BigBasket and B2B player Udaan deepened the bench; Meesho took social commerce public in December 2025. The warning light is Dunzo: Google's first Indian startup bet, dissolved January 2025 when quick-commerce economics turned.

India's electric two-wheeler war is run from Bengaluru. Ola Electric spun out of the ride-hailing giant in 2017, built the Futurefactory and took India's first big EV IPO (Aug 2024). Ather, incubated at IIT Madras and headquartered at IBC Knowledge Park, played the engineering-first hand — premium scooters, its own charging grid, a May 2025 listing. Between them (plus Bounce and Yulu in shared mobility) the city decides how India's streets electrify.

The newest cluster and the next bet. Krutrim — Bhavish Aggarwal's model-and-cloud venture — became India's first AI unicorn in January 2024; Sarvam AI was selected in 2025 to build India's sovereign large language model under the IndiaAI mission. They stand on a SaaS-and-devtools bench built quietly over a decade: Postman, founded in Bengaluru in 2014, became the world's default API platform; Hasura went from a local team to a Valley staple. The talent loop with the GCCs makes this the city's deepest AI pool.

Attention businesses, both triumphant and tragic. InMobi pivoted from SMS search to mobile ads and became India's first unicorn (2011); its Glance spin-off put content on a hundred million lock screens. Unacademy industrialised a college YouTube channel into HSR Layout's flagship. And Byju's — stadium coach to $22B edtech to near-zero write-down — is the cluster's cautionary monument, with gaming unicorn MPL and social app ShareChat filling out the bench.

UPI turned Bengaluru into a fintech capital. PhonePe, built by Flipkart alumni, carries roughly half of the world's busiest payment rail from its ORR offices. Razorpay (YC 2014) is the default payments stack for Indian startups. Cred monetises the prime end of the credit market from Indiranagar; Groww and Jupiter round out the bench. The outlier is Zerodha: India's biggest broker, bootstrapped from JP Nagar with zero venture capital — proof the ecosystem's best business never needed it. The 'reverse flip' of PhonePe, Groww and Razorpay back to Indian domicile signals where the IPOs will happen.
